We live in an increasingly unpredictable physical and social environment. Climate change, viral pandemics, wars, and mass migrations present significant challenges, while new technologies and media are transforming the ways we understand ourselves and think about our political situations. Which attitudes, skills, and values should we cultivate to enable us to respond well to the challenges of this changing world? The essays in this volume emphasise the importance of creativity, collaboration, understanding, and wisdom in dealing with one another and thinking about novel and unforeseen difficulties. Through better reasoning, we can reduce the influence of immediate responses and attune our responses to how the world really is and what really matters. The book aims to begin a conversation about how to foster better reasoning about new challenges through our education system, the structures of our organisations, the regulation of social-and- mass media, and the designs of buildings and urban spaces.
